Yep, you can power your web site via the sun. SolarHost claims to be the only internet company that is totally powered by renewable energy. SolarHost maintains a large, privately-owned solar power system, comprising 12 high-density 110W panels. After the immediate AC/DC power needs are met, excess power gets stored in a massive battery bank. The owners say it would take five days of darkness to shut them down. In case of catastrophic failure, a backup generator or grid power takes over in less than a minute.
Solarhost's use of solar energy may actually make their hosting service more reliable since they less vulnerable to power outages and blackouts.
